Question

Justin is considering two websites for downloading music.The costs are detailed here.

Website 1: a yearly fee of $30 and $1.50 for each download

Website 2: $2 for each download

What is a system of equations to represent the costs for one year?

Express your equations in the form of y=mx+b
where x is the number of downloads for the year and y is the total cost for the year.

Enter your equations in the boxes.

Website 2:

Answer 1

To express the costs for both websites in the form of equations, we can define \( y \) as the total cost for the year and \( x \) as the number of downloads.

**Website 1:**
The cost includes a yearly fee of $30 plus $1.50 for each download.
So, the equation can be expressed as:
\[
y = 1.5x + 30
\]

**Website 2:**
The cost is $2 for each download, with no yearly fee.
So, the equation can be expressed as:
\[
y = 2x
\]

Now, we can summarize the equations:

**Website 1:**
\[
y = 1.5x + 30
\]

**Website 2:**
\[
y = 2x
\]
